INCANDESCENT GAS-BURNER.

i SEEGIFICATION forming part of Letters Patent No. 672,722, datedAprl 23, 1901.

Application filed February 7, 1901. Serial No. 46.428. (No model.)

To LZZ whom, it may concern:

Be itknown that l, CLARENCE W. TAYLOR,

, a citizen of the United States,residing at Sioux j City, in the county of Woodbury and State of Iowa, have invented new and useful Improvements in Incandescent Gas-Burners, of which the following is a specification.

My invention relates to incandescent gasburners, the object of the same being to simplify and thereby cheapen the construction of this ,class of devices and to provide means whereby a more perfect combustion of the mixed gas and air may be obtained and a more thorough and effective heating of the same produced prior to the ignition, to the end that a higher state of incandescence may be produced in the mantle and a more perfeet light thereby obtained.

Other objects and advantages of the invention will hereinafter appear.

The invention consists of a mixing-chainber having an annular groove on the inside thereof and a heat radiator or conductor located wholly within said chamber and having a projecting ribpr beadjopposite the said groove or enlargement forming an offset in the narrow annular passage through which the mixed air and gas passes.

The invention also consists in certain features and details of construction and combinations of parts, which will be hereinafter more fully described and claimed.

In the drawing forming a part of this speciication the figure thereof is a vertical sectional view illustrating my invention. Y

The mixing-chamber l connects with a Bunsen tube or other source of supply for gas and air and has formed in the walls thereof, adjacent to its upper end, an annular horizontally-disposed groove or channel 2. Covering the upper end of the mixing-chamber is a foraminous disk 3, of wire-netting, perforated sheet metal, or other like material, to which is secured a heat radiator or conduetor 4. The said radiator 4 extends down into the mixing-chamber l and is of relatively large'dimensions, so as to form a narrow contracted passage 5 between it and the inner walls of said mixing-chamber, through which the air and gas pass to the point of ignition. The said radiator is wholly inelosed Within the mixing-chamber l, no portion of the same projecting above the diaphragm 3, which constitutes the top of said chamber. The same is formed opposite the groove or channel 2 with a projecting bead or rib t, which forms an offset in the contracted annular passage 5, through which the air and gas pass. The usual mantle is of course located above the disk 3.

Now, as will be readily understood, when the mixed air and gas is ignited at the foraminous disk 3, between the radiator 4 and the upper end of the mixing-chamber l, the heat thereof will serve to raise to incandescence the mantle4 and also heat the radiator 4 and the upper end of the mixing-chamber l. The mixed air and gas passing through the mixing-chamber l is brought into direct contact with the radiator 4, and a preliminary heating is thereby imparted to said mixed air and gas. By reason of the fact that the radiator 4 is of relatively large dimensions as compared with the mixing chamber l, in which it is located, and as the mixed air and gas has to pass through the contracted passage 5 said air and gas are brought into more intimate contact with the radiator 4, and consequently are raised to a higher heat. The result is that the combustion thereof at the foraminous disk 3 is more perfect and the heat produced from the ignition thereof is greater. This contact between the mixed air and gas and the heat-radiating surfaces of the device is made more complete by reason of the projecting bead or rib 6 on the radiator 4, which serves-to deflect the air and gas in flowing through the passage -that is, the air and gas first strike against the bottom walls of the rib or bead 6, taking up heat therefrom,andaredeflectedoutwardlyagainst the walls of the groove 2, which is near the upper end of the mixing-chamber l, and therefore subjected to great heat, and are then again deilected back against the side Walls of the radiator 4 above the rib or bead 6, adjacent to the upper end thereof. In this way the air and gas are caused to impinge against the radiating-sjirfaces of the device instead of passingin parallel lines along the same. A more eective preliminary heating of the air and gas is thereby effected.

From the foregoing description it will be observed that my improved device is made IOO \ struction is produced in which danger of clogduced toa minimiimand one in which a more ibinatio'n With a mixing-chamber havinganl up of fewlparts, which may be readily disconnected or appliedone'to the otherand a saving in the original cost of production thereby obtained. It will also be observed that a conging of the passages by carbon or rust is reeective preliminary heating ofthe mixed air and gas will be obtained prior lto the adi mission of the same Within the mantle. A more perfect combustion is thereby obtained and a more brilliant lightthereby produced. K

Having now described my invention, What I claim as new, and desire to secure byLe'tters' Patent, isl jl. vInan incandescent gas-burner, the cornannular grooveor channel on the inside therel of, of a foraininous vdis'k 'covering the upper end `of said chamber, and a heat-radiator 1ocated VWithinsaid chamber and provided with a projecting rib or bead opposite saidgroove or channel.

VIn testimony whereof I have hereuntoset my hand in presence of two subscribing witlSSeS.
